IMPROVEMENT IN STAVEl-DRESSING MACHINES- Spccificaiion forming part of Letters Patent No. 37,720, dated February 1T, lftil..

.To all whom, it may concern:

Beit known thatl, EDWARD HOLMES, of

the city of Buffalo and State. of New York,

assigner to EDWARD HOLMES und BRITMN HOLMES, of the same place, have inventedcertain new and useful Improvements in Stave-Dressing Machines,(as animprovement upon a stave-drcssing machine patented to Edward Holmes and Britain Holmes on the 19th day ot' February 1861-5) and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had l to the accompanyiu g drawings, making a. part of this specification, in which-- Figure l is a side elevation, and Fig. 2 1s a A the cutter-frame to the stationary or gear frame of the machine as to admit of a weight or equivalent to counterbala-nce the cutterframe; third, in projecting bars or rods from the stationary frame as a means of support and as a connection of the cutter-frame to the stationary frame, which bars are so constructed and connected to both frames as to admit ofa compound joint-like movement.

Letters of like name and kind refer to like parts in each of theiigures.

The main and stationary frame of the machine which supports the feeding mechinism is represented at A. Thecutter-t'rame, which is distinct from the main frame is represented at B. There is a shaft or journal,l1aving a central connection to the cutterframe and projecting from both sides of the f 1ame, as shown at c, upon which journal or journals the frame hangs, and balances thereon, or nearly so, so that it may oscillate or swing thereon.

D represents a rod or supporting and balancing bar-Lone upon each sido of the machine-which bars are for the purpose of supporting and balancing the cutter-frame. These bars have a connection to the main frame by means of a wrist or joint, as shown at d. Upon the end of this bar, which connects with the cutterframe isa thimblc or cap,- as shown at d2, which thimble forms a bearing l'or the journal-c. -The connection of this thimbleto the end ofthe bar is such as to allow it to turn on the bar slightly in an opposite direction to the joint d', so that the two form a compound or universal joint which will allow the. frame lto rise and fall in either direction. The frame being supported upon thejournals c, as aforesaid, which are free to move in their bearings in the thimble, will facilitate and make easy the rise and fall and oscillations et.' the frame in any direction, according to the particular condition ofcach stave to be dressed.'

Upon the opposite end or the har is a counterbalaucingfweight, E. '.Ihis weight may bc of sufficient gravity or have such advantage on the bar as to balance or poise thc cutterframe upon the wrist d', yso that thc cutterframe will rise and fall and oscillatc easily as the stave is being dressed. A yielding-pressu ure-plate is connected with the cutter-frame, so that the plate will slide up and down therein, as shown at F.l Two rods pass down through this plate and through the bottom of y the frame, one ot' which is shown at G. These rods have rubber-springs (or other springs muy be used) on thc lower end, as shown at h, which springs will render the plate sutliciently elastic and yielding to answer all the conditions required to accommodate itself to the condition ofthe stave-to be dressed.

This machine is particularly designed for dressing split or rived staves, which generally have crooked and winding surfaces and var v lunch in thickness before there ure dressed.

'lhc improvements which l have introduced and herein described appear to meet and au 'swer all the conditions for a complete and successful dressing ofcvcry quality ol' split or rived staves.

The other parts ofthe machine are suh-4 stantially like the aforesaid machinepatented to Edward and Britain Holmes on the 19th ot February, .15561, and do not therefore require a particular description. l will only rcler to some ofthe more principal parts by lette-r l,v lyielding; mouth-piece; J,`uppcr cutter-head 5 J', drivingpnlleys for upper cutter '5 J2,-driving-pulley l'or lowerI cutter; K, yzuljnsiingA screws L; rod,(hav'in, g rubber-springs,)whieh connects the upper part ot' the -cutter-frame vto the stationary frame; lll, main driving` guides; R, convex bed-plate; S,Weighted lever, Which (through the rods S) is connected to the pulley; N, spur-wheel on shaft of lower feedi ing as the varying conditions vof the stave to roller N, pinion N2, pinion on drivingi be dressed inzlyArequire.
